CPH did some market research a while back and the overwhelming response from LCMS pastors was "more Gottesdienst".....er, wait, not that, it was: "more practical, how to studies." At any rate, we Gottesdienst editors do try to keep busy producing resources in various venues, and when we get the nod from the official folks in St. Louis all the better. The new series from CPH is aimed at the Bible Class-going lay person and focuses on "Five Things You Can Do" in a specific area of the Christian life: understand the Bible better, get more out of church, etc. The result is a series of 96 pages books with five chapters plus introduction and conclusion. They are suitable for either Bible Studies or simply to read.
I was assigned what was perhaps the most general topic "how to lead a Jesus-centered life." I can't speak for the other authors, but the editor(s) assigned to me were very good about letting me write the book as I wanted. I hope it can be of use to you: check it out here.
